Acute onset movement disorders in diabetes mellitus: A clinical series of 59 patients

Background and purposeNo previous study has assessed the frequency and clinical–radiological characteristics of patients with diabetes mellitus (DM) and acute onset nonchoreic and nonballistic movements. We conducted a prospective study to investigate the spectrum of acute onset movement disorders in DM.MethodsWe recruited all the patients with acute onset movement disorders and hyperglycemia who attended the wards of three hospitals in West Bengal, India from August 2014 to July 2021.ResultsAmong the 59 patients (mean age = 55.4 ± 14.3 years, 52.5% men) who were included, 41 (69.5%) had choreic or ballistic movements, and 18 (30.5%) had nonchoreic and nonballistic movements. Ballism was the most common movement disorder (n = 18, 30.5%), followed by pure chorea (n = 15, 25.4%), choreoathetosis (n = 8, 13.6%), tremor (n = 5, 8.5%), hemifacial spasm (n = 3, 5.1%), parkinsonism (n = 3, 5.1%), myoclonus (n = 3, 5.1%), dystonia (n = 2, 3.4%), and restless leg syndrome (n = 2, 3.4%). The mean duration of DM was 9.8 ± 11.4 years (89.8% of the patients had type 2 DM). Nonketotic hyperglycemia was frequently (76.3%) detected. The majority (55.9%) had no magnetic resonance imaging (MRI) changes; the remaining showed striatal hyperintensity. Eight patients with MRI changes exhibited discordance with sidedness of movements. Most of the patients (76.3%) recovered completely.ConclusionsThis is the largest clinical series depicting the clinical–radiological spectrum of acute onset movement disorders in DM. Of note was that almost one third of patients had nonchoreic and nonballistic movements. Our findings highlight the importance of a capillary blood glucose measurement in patients with acute or subacute onset movement disorders, irrespective of their past glycemic status.

IDF21-0171 Study of renal Profile In diabetic patient: Retrospective study among 48 patients

Background: Diabetes is considered the commonest cause of end-stage renal disease. The increasing incidence of obesity and an ageing population, together, will lead to a greater number of people with diabetes associated with chronic kidney disease that could either be secondary to diabetic nephropathy or of different aetiology. Based on data from the UK and USA, up to 40% of people with diabetes will develop chronic kidney disease. Pooled data from 54 countries reveal that more than 80% of cases of end-stage renal disease (ESRD) are caused by diabetes, hypertension or a combination of both. Aim: To study of renal profile in diabetic patient. Method: This was a retrospective analytical and descriptive study conducted at internal medicine department on 13 months. The total of 48 diabetic patients were included in this study. Patient data including patient characteristics, and hypertension, duration of diabetes, creatinine level, blood pressure, blood glucose level, HbA1c. The eGFR (Glomerular Filtration Rate) has been determined using the MDRD equation (Modification of Diet in Renal Disease). Renal disease was staged according to the 2012 High Authority of Health France guidelines. The statistical analysis was carried out using Epi-Info7 software. Results: There were 48 diabetic patients with a mean age of 66±10 years with male predilection (77%) compared to females (23%). Mean duration of diabetes mellitus was 15±9 years. Most of patients (93.75%) were type2 mellitus diabetes. The majority of patients were on insulin (42.92%).Ten (20.83%) were on oral hypoglycemic agents (OHA), and eleven patients (22.92%) were on combined insulin and OHA. Hypertension was found in 50% of diabetic patients. Mean duration of hypertension was 11±10years. Metabolic syndrome was found in 80%. The mean GFR (Glomerular Filtration Rate) in diabetic patients according MDRD equation was 69±41 ml/min/1.73m2. There were 44 patients (92%) with chronic renal disease ,with mean of BMI 26±5 kg/m2, mean of diastolic pressure 73±10 mmHg, mean of systolic pressure 125±18 mmHg , mean of Haemoglobin was10±2 g/dl, mean of fasting blood glucose 1.71±0.79g/l, mean of post prandial blood glucose 2.47±0.77g/l, mean of HBA1C 9±3%, mean of creatinine was 19±22 mg/l, mean of creatinine clearance was 69±41 ml/min/1.73m2. There was 32% with CKD1, 27% with CKD2, 14% with CKD4, 9% with CKD3A, 9% with CKD3B, and 9% with CKD5 stage of renal failure. Mean of HBA1C was 9±4 % in patients with CKD1, and patients in CKD5 with a mean HBA1C 13±2. Discussion: Kidney disease is far more common in people with diabetes than in people without diabetes. Diabetes is one of the leading causes of chronic kidney disease (CKD). Diabetes, hypertension and kidney failure are highly interlinked. On the one hand, type 2 diabetes is a leading cause of kidney failure, which is a risk for hypertension, and on the other, hypertension can often precede CKD and contribute to the progression of kidney disease. Both diabetes and CKD are strongly associated with cardiovascular disease (CVD) and therefore, the major component in their management is control of CVD risk factors such as hypertension and high blood glucose (hyperglycaemia). In our study population, advanced age was found. They were older, with overweight, and had a longer diabetes and hypertension duration. Diabetic with CKD patients also had a poor glycemic control. This strongly calls for effective screening for diabetic population at risk.

To Determine the Frequency of Different Complex Coronary Lesions in Diabetic Patients

Background: Diabetic people have an excessive amount of coronary atherosclerosis. Diabetes mellitus is a strong predictor of mortality and MI in both men and women. It's unclear whether diabetics and non-diabetics have different rates of complicated coronary lesions such bifurcation and ostial lesions. Objective: To find out how often different types of complicated coronary lesions are in diabetic people. Methodology: 136 individuals were enrolled in this study. All patients had coronary angiography using the conventional femoral or radial artery technique. Angiographic data was obtained by two interventional cardiologists with 3 years of post-fellowship experience interpreting angiograms. Data on complicated coronary lesions was collected. It has a significant p-value (0.05), indicating that there is a significant difference in this disorder between the two groups. Results: The mean age of the 136 patients was 47.3±12.2 years (range 25 to 70 years). There were 71 males (52.2%) and 65 females (47.8%). Mean BMI was 25.9±1.3 kg/m2, mean duration of diabetes mellitus was 7.5±3.5 year, mean weight was 75.7±5.1 and mean height was 5.3±0.6 m. Coronary artery lesions were as follows: bifurcation lesions 85 (62.5%), ostial lesion 32 (23.5% and LMCA lesions 19 (14%). Stratification with regard to age, gender, BMI and duration of diabetes was also carried out. Conclusion: In diabetic patients, complicated coronary lesions such as bifurcation and ostial lesions were shown to be substantially more prevalent than LMCA lesions.

LUCENTIS IN THE TREATMENT OF DIABETIC MACULAR EDEMA, TWO-YEAR RESULTS.

To evaluate, on the basis of two-year observations, the effectiveness of intravitreal treatment with Ranibizumab in patients with diabetic macular edema (DME) unresponsive to the previous laser treatment. Cohort and Methods: A retrospective study evaluates 29 eyes of 29 patients with diffuse DME unresponsive to their previous laser treatment. The group of the patients consisted of 16 males (55.1%) and 13 females (44.8%); their mean age was 71.3. The mean duration of diabetes mellitus was 13 years (3-20). 19 patients (65.5%) were treated with insulin, 10 patients (34.4%) were treated with peroral antidiabetics (PAD); the mean HbA1c value was 52 mmol/l. The treatment was started with 3 initial doses of intravitreal injections of Ranibizumab 0.5 mg. There was a one- -month interval between the applications. Subsequent evaluations and administrations of the following injections were made in the pro re nata (PRN) mode; the check-ups were carried out every month during the first year and on average every 3 months in the second year. The monitored parameters: the best corrected visual acuity (BCVA) measured on ETRDS (Early Treatment Diabetic Retinopathy Study) optotypes, the central retinal thickness (CRT). These parameters were monitored prior to the treatment and then in the 3rd, 6th, 9th, 12th, 18th and 24th months. A statistically significant improvement in the mean value of BCVA was detected. From the initial 65.4 ±10.61 letters it improved by 11.2 letters (p.

Cognitive Impairment in Type 2 Diabetes Mellitus.

ObjectiveTo determine the incidence of cognitive impairment established on the mini-mental state assessment in type 2 diabetic patients presenting at Holy Family Hospital, Rawalpindi.Materials and methodsThis cross-sectional descriptive study was carried out from June 2019 to December 2019. Individuals with a diagnosis of type 2 diabetes mellitus were included, and detailed history, physical examination, and biochemical variables were noted. They were assessed through Mini-Mental State Examination (MMSE) (Urdu translation) to look for the primary outcome variable, i.e., cognitive impairment. All patients with type 2 diabetes mellitus diagnosed at least one year back, irrespective of gender, were included in this investigation. Patients with a previous history of head injury, epilepsy, stroke, those on an antidepressant or antipsychotic medications, those with deranged renal function tests, and those already diagnosed with dementia were excluded from the study.ResultsThree hundred thirty-two patients meeting the inclusion criteria were included in the study. The mean ± standard deviation age of the study population was 65.32 ± 11.33 years, with maximum age being 80 years and the minimum being 50 years. Two hundred patients (60.24%) were below 65 years of age, and 132 patients (39.76%) were 65 years of age or above. Two hundred sixteen (65.06%) were males, and 116 (34.96%) were females. The mean duration of diabetes mellitus (DM) was 10.17 ± 4.81. The mean MMSE score was 22.69 ± 5.26. Out of 332 patients, 81 (24.4%) patients had cognitive impairment. Patients who were 65 or older had a significantly higher proportion of cognitive impairment, compared to those below 65 years of age (p-value = 0.0214). There was no significant difference in the proportion of cognitively impaired patients between males and females (p-value = 0.2497). Similarly, there was no significant difference between those who were diagnosed with type 2 diabetes for 10 years or more and those who were diagnosed less than 10 years ago (p-value = 0.3791).ConclusionCognitive impairment is common in individuals having type 2 diabetes mellitus. It is also associated with the increasing age of diabetic patients. However, cognitive impairment in type 2 diabetes mellitus is not associated with gender. In addition, there is no significant difference in cognitive impairment between the patients who were diagnosed with diabetes more than 10 years ago and those who had it diagnosed less than 10 years ago.

Prevalence and predictors of thyroid dysfunction amongst patients with Type 2 diabetes mellitus in Pakistan.

ABSTRACTIntroduction:Diabetes and thyroid disorders are the two most common disorders amongst endocrine diseases. Uncontrolled diabetes mellitus (DM) may disturb thyroid metabolism by disturbing the levels of thyroid hormones in the plasma. This study was undertaken to determine the prevalence and thyroid dysfunction in type 2 diabetic population presenting in a public sector tertiary care teaching hospital.Materials and Methods:This descriptive cross-sectional study was conducted in Civil Hospital Karachi (CHK) in the department of medicine from October 01, 2018, to March 31, 2019. The study population consisted of 317 patients diagnosed with DM type 2 based on American Diabetes Association (ADA) criteria. Patients with fasting blood sugar ≥ 126 mg/dL, or HbA1c >6.5 (%), and 2 h postprandial blood glucose levels >200 mg/dL were included. After a minimum of 8 h of fasting, plasma samples of patients were collected and sent for fasting blood glucose, HbA1c, FT3, FT4, and thyroid-stimulating hormone (TSH). Descriptive statistics were calculated. Post-stratification Chi-squared test was applied, and a P value of ≤ 0.05 was considered significant.Results:Among all enrolled DM type 2 patients, 207 (65.3%) were male with a mean age of 46.54 ± 8.72 years. Mean fasting blood sugar (FBS), random blood sugar (RBS), and HbA1c were 212.76 ± 26.91 (mg/dL), 328.89 ± 52.89 (mg/dL), and 9.43 ± 2.47 (%), respectively. The mean duration of DM was 7.81 ± 3.15 years. Mean FT3, FT4, and TSH were 113.13 ± 44.40 (ng/dL), 7.63 ± 3.11 (mg/dL) and 2.64 ± 2.57 (mIU/mL), respectively. In the present study, 55 (17.4%) patients had subclinical hypothyroidism, 27 (8.5%) had hypothyroidism, 19 (6.0%) had hyperthyroidism, and 16 (5.0%) had subclinical hyperthyroidism. Significant association of thyroid dysfunction was established with age group, female gender, and family history of thyroid dysfunction (P =< 0.001).Conclusion:The prevalence of thyroid dysfunction is higher among patients with type 2 diabetes mellitus (T2DM), in which hypothyroidism was the most common dysfunction with more prevalence among female patients.

A Study of Cardiovascular Autonomic Neuropathy in Adult Patients with Diabetes Mellitus at Levy Mwanawasa University Teaching Hospital

Cardiac autonomic neuropathy (CAN) is the diminished capacity of autonomic regulation of the cardiovascular system occurring in the presence of diabetes mellitus (DM) and in the absence of other aetiologies. Diabetes mellitus is a well- known cause of peripheral neuropathy. However, in comparison to somatic neuropathy, autonomic neuropathy is an under-diagnosed and under-treated chronic complication of diabetes mellitus despite its serious and significant contribution to morbidity and mortality in the diabetes mellitus population. A variety of tests, based on evaluation of the cardiovascular reflexes triggered by performing specific provocative manoeuvres, have been proposed to measure autonomic function. This study used four cardiovascular reflex tests to estimate appropriate autonomic function by examining heart rate, heart rate variation and the baroreceptor reflex. The aim of this study was to determine the presence of cardiovascular autonomic neuropathy in adult patients with diabetes mellitus at Levy Mwanawasa University Teaching Hospital in Lusaka, Zambia. Adult patients with diabetes mellitus, aged between 21 and 70 years, participated in this cross-sectional study. Four, non-invasive, cardiac autonomic reflex tests to assess for cardiac autonomic neuropathy were employed according to Ewing’s method. The parasympathetic function was analysed based on the heart rate response to paced deep breathing and to Valsalva manoeuvring. The sympathetic function was assessed by measuring heart rate and blood pressure response to postural change. Ewing`s criteria was used for the categorisation of cardiac autonomic neuropathy. Data were analysed using SPSS version 20. Continuous data were presented as means and standard deviation. Categorical data were analysed using a Fishers’ Exact Test (χ2) and a logistic regression was performed to verify the effects of diabetes mellitus’ duration, sex and age on the probability that the participants have cardiac autonomic neuropathy. A total of 52 patients participated in the study. The prevalence of Cardiac autonomic neuropathy was 48.1%. Out of 52 patients, 42.3% had definite cardiac autonomic neuropathy and 5.8% had severe cardiac autonomic neuropathy. Early cardiac autonomic neuropathy was observed in 34.6% of patients while 17.3% had no signs of cardiac autonomic neuropathy. The mean age of patients with cardiac autonomic neuropathy was 54.44 ± 10.90 years and the mean duration of diabetes mellitus from diagnosis was 5.36 ± 6.78 years. The probability of developing cardiac autonomic neuropathy increased with increasing age and hypertensive participants were more likely develop cardiac autonomic neuropathy (ѵ = 5.82, p = .001). In conclusion, cardiac autonomic neuropathy was present in a significant proportion of adult patients with diabetes mellitus at Levy Mwanawasa University Teaching Hospital, reflecting the increased morbidity encountered by this population. In order to improve patient quality of life and reduce disease burden, screening for cardiac autonomic neuropathy should be implemented using cardiovascular autonomic reflex tests which are relatively simple, safe and affordable.

Comparative Doppler Ultrasound Findings of Foot Arteries in Patients with Type 2 Diabetes Mellitus and Normoglycaemic Patients

Aim of the Study:The aim of this study was to investigate lower extremity peripheral artery disease (LEPAD) in the foot arteries of patients with type 2 diabetes mellitus, with and without clinical symptoms of arterial insufficiency, using triplex Doppler ultrasound.Materials and Methods:Forty-seven consecutive adult subjects with type 2 diabetes mellitus (T2DM) and 47 age-matched and sex-matched non-diabetic controls were recruited (94 limbs each). Ankle-brachial index (ABI), fasting blood glucose assay, glycated haemoglobin assay and triplex sonography of the dorsalis pedis artery (DPA) and the distal posterior tibial artery (PTA) in both feet were performed.Results:The mean age of the subjects and controls were 60.21 ± 7.68 years and 56.81 ± 9.05 years (P > 0.05). The mean duration of diabetes mellitus was 10.4 ± 5.8 years. Crampy calf pain was the most common presenting symptom. Twenty-one (22.3%) of the 94 limbs of T2DM subjects had an abnormal ABI. Abnormal triplex Doppler waveform was seen in more than half of the PTA (57/94; 60.6%) and DPA (55/94; 58.5%). Forty-one (43.6%) of the 94 diabetic limbs had plaques in the PTA, while plaques were present in the DPA of 52 (55.3%) diabetic limbs.Conclusion:LEPAD is common in T2DM with a higher prevalence on triplex Doppler sonography compared to ABI values.

Health-related quality of life of persons with diabetic foot ulcers in a cosmopolitan city in northwestern Nigeria.

Diabetic foot ulcer is one of the most serious and disabling complications of diabetes mellitus (DM). It is a major source of morbidity, mortality, and a leading cause of hospitalization. It constitutes a major burden to the patient, family, and health-care system as well as impairs quality of life (QoL). The aim of this study was to determine the QoL of persons with diabetic foot ulcers attending two major hospitals in a cosmopolitan city in northwestern Nigeria. We conducted a descriptive cross-sectional study at the diabetes outpatient clinics and wards of two major hospitals in Kano, Northwestern Nigeria. Sociodemographic characteristics, type of DM, duration of DM, and the presence of risk factors for foot ulcers were assessed. The QoL of patients with and without foot ulcer was determined a well-validated questionnaire for chronic diseases, short form 36 (SF 36) health-related QoL questionnaire. We recruited 394 patients with DM (163 males and 231 females) with mean age and duration of DM of 50.8 ± 12.5 years and 7.72 ± 6.65 years, respectively. Ninety-five percent of the study participants had type 2 DM. Foot ulcers were present in 57 (14.5%) study participants. The QoL was generally poor (P < 0.001) in patients with DFU, compared with those without DFU in all domains of the SF 36, that indicated poor QoL in the physical, mental, and emotional well-being of the patients. Diabetic foot ulcers are quite common and impart significantly on the QoL of persons with DM affecting their physical, mental, and emotional well-being. Early detection and management of foot ulcers will reduce the burden of the disease and improve the QoL of affected individuals.

Safety of Insulin Degludec/Insulin Aspart in Patients with Diabetes Mellitus over a Period of 1 Year during Routine Clinical Care in India: SMART (Study of Management of Diabetes with Ryzodeg™ Treatment).

This post-authorization study was conducted to evaluate the safety of insulin degludec/insulin aspart (IDegAsp) in adult patients with diabetes mellitus (DM) during routine clinical care under a real-world setting in India. Eligible patients received IDegAsp for a minimum of 12 months during routine clinical management. Data were collected at 0, 3, 6, and 12 months. In total, 1029 adult patients with DM were included; 65.2% (n = 671) were men; mean age was 55.0 ± 12.2 years, and the mean duration of diabetes mellitus was 10.8 ± 7.4 years. Thirty adverse events were reported in 23 patients (2.2%) during the follow-up: two adverse events in two patients were serious with fatal outcomes, which were unrelated to IDegAsp use. At baseline, there were 176 confirmed hypoglycemic events in 67 (6.7%) patients while they were on their previous treatment options. At 12 months of treatment with IDegAsp, 11 confirmed hypoglycemic events were reported in 11 (1.1%) patients since the previous visit; there were no reported episodes of severe hypoglycemia. Mean glycosylated hemoglobin value reduced from 9.5% ± 1.8% at baseline to 7.7% ± 1.1% at 12 months. This study showed the safety of IDegAsp in patients with diabetes mellitus over a period of 1 year during routine clinical care.

Association of Cardio-Ankle Vascular Index (CAVI) and Duration of Diabetes Mellitus in the STOP (Semaglutide Treatment on Coronary Plaque Progression) Randomized Control Trial

IntroductionCardio‐ankle vascular index(CAVI) is a novel index that measures arterial stiffness noninvasively. Recent studies demonstrated CAVI to be a predictor for coronary artery disease(CAD). Patients with Type-2 diabetes mellitus(DM) develop arterial stiffening which contributes to the CAD complications associated with DM. However, a comprehensive assessment of the association of CAVI and DM has not been reported. MethodsThe STOP trial randomized patients with DM and presence of coronary plaque on CCTA to Semaglutide 1mg once weekly or placebo. CAVI was measured using the VaSera(Fukuda Denshi, Tokyo, Japan). Non-invasive blood pressure, Pulse Wave Velocity and Heart Sound Measuring were integrated to compute CAVI. Multivariate linear regression was used to examine the association of baseline CAVI and duration of diabetes. ResultsIn 98 randomized STOP subjects, mean age was 56.8±8.3 yrs and 60 (61%) were male. Of these, 81 (83%) had hyperlipidemia, 81 (83%) had hypertension, 13 (13%) were current-smokers, and 31 (32%) were former-smokers. The mean duration of DM was 16.3±7.5 yrs. In an unadjusted linear regression analysis, there was a positive linear relationship between duration of DM and CAVI (p=0.036). However, upon further analysis with adjustment for age, gender, body mass index, HLD, HTN, and past smoking, the association was no longer significant (p=0.189). ConclusionCAVI has a linear association with the duration of Diabetes. The lack of statistical significance on multivariate adjusted analysis could be due to the small sample size. Future studies should assess the prognostic role of CAVI in patients with DM.

Influence of glycaemic control on macular thickness in diabetic retinopathy.

IntroductionDiabetic macular oedema (DME) is one of the major cause of decreased visual acuity in patients with diabetic retinopathy. Poor glycaemic control is associated with increased incidence of DME.MethodsA total of 112 eyes of 112 patients were studied in this cross‐sectional study and were classified into three groups based on HbA1c: group 1 included patients with good glycaemic control (HbA1c ≤7%), group 2 included patients with moderate glycaemic control (HbA1c between 7% and 9%) and group 3 included patients with poor glycaemic control (HbA1c ≥9%).ResultsWe included 112 eyes of 112 patients. The mean duration of diabetes mellitus (DM) was 11.37 years. In statistical analysis, CMT (mean 188.80 ± 27.64 μm) positively correlated with mean HbA1c level (7.95 ± 1.29%) (r = 0.238, p < .05). There was a significant difference in CMT values among the three groups of HbA1c (F (2,109) = 19.39, p < .001). Post hoc analysis showed statistical significance between HbA1c≤7% and HbA1c ≥9% group and HbA1c 7%–9% and ≥9% group. However, statistical significance was not found among HbA1c ≤7% group and HbA1c 7%–9% group. Multiple regression analyses showed a significant correlation between CMT and HbA1c after adjusting for age and duration of diabetes.ConclusionSerum HbA1c level has a significant correlation with CMT in diabetic patients.

Early functional and microcirculatory changes in patients with type 1 diabetes mellitus and no apparent diabetic retinopathy

BACKGROUND: Diabetic retinopathy (DR) is the leading complication of diabetes mellitus (DM) which is reported to affect more than one-third of the global diabetic population. Optical coherence tomography angiography (OCT-A) can help to reveal early biomarkers of DR to improve current diagnostic approach.AIMS: To evaluate early visual functions deficiency and OCT-A changes in patients with type 1 DM (T1DM) without clinical signs of DR.MATERIALS AND METHODS. 74 eyes of 40 T1DM patients with no apparent DR and 49 eyes of 28 healthy volunteers were included in the study. The mean duration of DM was 11,7 ± 6,1 years. All participants underwent standard ophthalmological examination, low-luminance visual acuity (LLVA) assessment, 7-field fundus photography, OCT and OCT-A. We analyzed LLVA deficit as a marker of visual function. For OCT-A scans we evaluated foveal avascular zone (FAZ) area (mm2), acircularity index (AI), vessel density (VD), skeletonized density (SD) and vessel diameter index (VDI) in superficial vascular plexus (SVP), intermediate capillary plexus (ICP) and deep capillary plexus (DCP).RESULTS: LLVA deficit was significantly higher in T1DM patients (0,16±0,05 vs 0,10±0,04, p&lt;0,0001). We also detected a significant difference in AI level (11,47 ± 0,24 vs 1,31 ± 0,15, p&lt;0,0001). VD was significantly lower in T1DM patients in SVP (25,37 ± 2,24%, vs 26,67 ± 1,81%, p=0,028) and DCP (17,22 ± 3,10 % vs 18,29 ± 1,95%, p=0,015)CONCLUSIONS: Our results demonstrate early visual functions deficiency and OCT-A changes at the preclinical stage of DR. The prognostic value of these findings will be studied during longitudinal observation.

BACKGROUND Metformin is reported to induce vitamin B12 deficiency and distinguishing peripheral neuropathy due to vitamin B12 deficiency from diabetic peripheral neuropathy can be challenging. The present study was conducted to assess and compare the clinical presentation of diabetic patients taking metformin with those not taking metformin using Toronto clinical scoring system (TCSS). METHODS This cross-sectional study included 60 patients with diabetes mellitus, 30 patients on metformin therapy (at least 6 months) and 30 patients not on metformin use. Clinical presentation of the patients was assessed using the TCSS. Patients were diagnosed according to the American diabetic association criteria. RESULTS The mean age of the patients in metformin and non-metformin group was 57.27 ± 9.38 and 58.63 ± 10.27 years respectively. Gender distribution was observed to be similar in both the study groups. Mean duration of diabetes mellitus was found to be similar in both the study groups (5.4 ± 1.01 vs 5.2 ± 1.27 years) and duration of peripheral neuropathy was also found to be similar in the two study groups (3.2 ± 1.6 vs 3.3 ± 1.5 years). Numbness was observed in maximum number of cases in both study groups. It was seen in 100 % (n = 30) patients on metformin drug while in 90 % (n = 27) patients without metformin. Pain accounts to be approximately 77 % (n = 23) and 24 % (n = 7) in patients on metformin and without metformin. Neuropathic symptoms and neuropathic reflex scoring appear to be higher common in patients on metformin as compared to those without metformin. Mean pain score was found to be significantly higher among patients on metformin as compared to those not on metformin (8.43 ± 2.13 vs 4.03 ± 3.13; P value &lt; 0.001). CONCLUSIONS Our results show that patients on metformin for diabetes mellitus experience higher neuropathic symptoms as compared to those not taking metformin.

BACKGROUND In diabetes mellitus microvascular damages at various end-organ frequently occurs and leads to development of diabetic nephropathy as well as diabetic retinopathy. Diabetic nephropathy ultimately causes end stage renal disease. Diabetic retinopathy even at its earlier stage is easily suspected by simple clinical examination in any ophthalmological clinic. We wanted to study the relationship between various stages of diabetic retinopathy with diabetic nephropathy. METHODS 1209 diagnosed patients of diabetic mellitus were screened for presence of diabetic retinopathy. First comprehensive ophthalmological examination including slit-lamp bimicroscopy and indirect ophthalmoscopy were done and then clinically typing of diabetic retinopathy according to ETDRS classification was done. Then all diagnosed case of diabetic retinopathy further examined for blood Glycosylated haemoglobin, blood urea and serum creatinine to detect diabetic nephropathy. RESULTS 273 patients were included in this study. Average age of patients was 64.6 years with mean duration of diabetes mellitus was 7.4 years. Patients suffering from severe NPDR and PDR had association with poor control of blood glycosylated haemoglobin. Patients with mild NPDR 31.1 %, Moderate NPDR 52.3 %, severe NPDR 67.4 % and in PDR 65.2 % patient had blood urea more than 40 mg / dl. In mild NPDR group 32.2 %, moderate NPDR 55.4 %, severe NPDR 67.4 % and in PDR group 63.9 % patients had serum creatinine more than 1.5 mg / dl. We have found statistically significant correlation between HbA1c level and severity of diabetic retinopathy. Prevalence of nephropathy increased with increments in the grade of retinopathy. CONCLUSIONS A significant number of patients with severe NPDR or PDR had increased blood urea and serum creatinine level. Clinical grading of diabetic retinopathy gives us a clue about the presence of diabetic nephropathy. As diagnosis of diabetic retinopathy is simple and straight forward clinical procedure and it can be done all ophthalmological se up, we recommend all patient with diabetic retinopathy must be screened for nephropathy.

Evaluation of Macular and Retinal Nerve Fiber Layer Thickness in Children with Type 1 Diabetes Mellitus without Retinopathy.

PurposeThere are limited data from Asian countries regarding retinal thickness in children with type 1 diabetes mellitus (T1DM). This study aimed to compare the macular and retinal nerve fiber layer (RNFL) parameters between diabetic children without retinopathy and non-diabetic healthy children. We also evaluated the factors associated with RNFL thickness in children with T1DM.MethodsA comparative cross-sectional study was conducted among children with T1DM and healthy children aged 7 to 17 years old in Hospital Universiti Sains Malaysia from 2017 to 2019. Children with retinal disease or glaucoma were excluded. Macular and RNFL thicknesses were measured using spectral-domain optical coherence tomography. Demographic information, duration of diabetes, blood pressure, body mass index, visual acuity, and retinal examination findings were documented. Glycosylated hemoglobin levels, renal function, and blood lipid levels were also collected.ResultsForty-one children with T1DM and 80 age- and sex-matched children were enrolled. Both sexes were affected. Mean duration of diabetes mellitus was 3.66 years. The mean glycated hemoglobin levels in the T1DM group was 9.99%. The mean macular and RNFL thicknesses in children with T1DM were 277.56 (15.82) μm and 98.85 (12.05) μm, respectively. Children with T1DM had a significantly thinner average macula, superior outer macula, nasal outer macula, mean RNFL, and inferior RNFL thickness compared to controls (p < 0.05). There was a significant association between nephropathy and the mean RNFL thickness.ConclusionsChildren with T1DM had significantly decreased mean macular and RNFL thicknesses. Nephropathy is associated with an increased RNFL thickness.

Implementation and evaluation of a team approach to managing diabetes mellitus and diabetic retinopathy in the South African district health system

Background: Diabetic retinopathy (DR) screening programmes have been developed and implemented in different countries based on availability of resources. Most protocols developed for DR have been solely dedicated to DR screening without involving systemic screening.Aim: To implement and evaluate a DR screening model utilising a team of healthcare practitioners (HCPs) to manage diabetes mellitus (DM) to reduce DR progression.Setting: Primary healthcare clinics and Voortrekker hospital in Waterberg district of Limpopo province.Methods: A cross-sectional study was conducted, in which a total of 107 patients with DM from seven clinics consented to participation. A proposed DR screening model was implemented where patients with DM were screened for systemic complications at clinics and referred to Voortrekker district hospital for retinal photography. Questionnaire responses evaluated the success of the screening process and operational challenges.Results: From the study population, 32 (29.1%) were male and 75 (70.1%) were female. The mean age of patients was 63.7 years with a mean weight of 80.69 kg. The mean duration of DM was 9.26 years and the mean haemoglobin A1c (HbA1c) level was 9.7%. From the 47 patients who had visual acuity less than 6/9, 74.5% had refractive error. About 10% (9.4%) had DR or diabetic macular oedema (DME) and 38.3% had other lesions. Referral to an ophthalmologist was necessary in 36.5% of cases.Conclusion: The implementation of a team approach to co-manage DM and DR utilising the developed protocol improved the quality of care for patients with DM in the district health system.

Association between lipid indices and 10-year cardiovascular risk of a cohort of black Africans living with type 2 diabetes mellitus

Introduction Diabetes mellitus is an established cardiovascular risk factor. Diabetes mellitus impairs lipid metabolism and enhances atherosclerosis development. Absolute lipid parameter are inadequate in predicting cardiovascular risk and some lipid indices have been reported to circumvent this deficiency. The objective of the study was to determine the association between these lipid indices and 10-year cardiovascular risk among black Africans with diabetes.&#x0D; Methods Seventy individuals (35 males and 35 females) living with diabetes who attended the diabetes clinic of a referral hospital in South-western Nigeria were recruited to the study. Ethical approval and participants’ informed consent were duly obtained. Fasting plasma glucose, fasting lipid profile and glycated haemoglobin were done using appropriate laboratory techniques. Atherogenic index of plasma, atherogenic coefficient, Castelli’s risk index I, Castelli’s risk index II and CHOLindex were calculated using appropriate formulae. QRISK 3 score was obtained using a validated calculator. The association between QRISK 3 and the lipid indices was determined using Pearson’s correlation.&#x0D; Results The mean age of the participants was 53.34 ± 9.57 years. The mean duration of diabetes mellitus among the participants was 6.29 ± 2.78 years. The mean HbA1c and FPG were 6.98±0.72% and 6.32±0.87 mmol/L respectively. The mean QRISK 3 score was 7.58±4.80. There was a statistically significant and positive correlation between QRISK 3 score and AIP, AC, CR I and CR II. CHOLindex did not significantly correlate with QRISK 3 score.&#x0D; Conclusion Among black Africans with diabetes, lipid indices (AIP, AC, CR I and CR II) significantly correlated with QRISK 3 score and therefore may be used as cheap markers of 10-year cardiovascular risk in these individuals.

Influence of Emergency Declaration Over Coronavirus Disease 2019 on Plasma Glucose Control of Patients With Diabetes Mellitus

COVID-19 pandemic poses problems that not only concern the economy but also the health of people all over the world. In Japan, despite the declaration of a “state of emergency”, no lockdown was implemented, and a request for self-restraint and avoidance of non-essential trips was instead issued. After a month, the state of emergency was lifted. Because patients with diabetes mellitus (DM) were forced to stay during the state of emergency, resulting in a lack of physical activity, concerns about their glycemic control were raised. Therefore, glycated hemoglobin (HbA1c) levels during different time periods were compared (May 2018, March 2019, June 2019, July 2019, May 2019, March 2020, June 2020, July 2020). We analyzed 165 patients with DM. The mean age of subjects was 67.8 + 11.5 years. Male comprised 67.3% of the participants. The mean body weight was 65.6 + 14.6 kg on July 2019 and 66.1 + 15.2 kg on July 2020. The mean body mass index (BMI) was 24.4 + 3.6 kg/m2 on July 2019 and 24.4 + 3.6 on July 2020. Patients with Type 2 DM (T2DM) comprised 90% of the participants, while the rest had T1DM. Mean duration of DM was 12.0 + 7.4 years. In order to assess the effect of the self-restraint on plasma glucose control, HbA1c levels during these periods were compared: May 2018, March 2019, June 2019, July 2019 (one year before COVID-19 pandemic.), and May 2019, March 2020, June 2020, July 2020 (The last three months during COVID-19). March 2020 is corresponded to a period before the request for self-restraint, while June and July 2020 corresponded to the periods right after the end of self-restraint. We also compared HbA1c levels between May 2019 and July 2020 using the Self-Monitoring of Blood Glucose (SMBG) to assess whether SMBG affected plasma glucose control during the period of self-restraint. HbA1c levels in May 2018, March 2019, June 2019, July 2019, May 2019, March 2020, June 2020, July 2020, were 7.32 + 1.23, 7.44 + 1.20, 7.16 + 1.06, 7.01 + 1.05, 7.23 + 1.06, 7.45 + 1.18, 7.15 + 10.7, and 7.11 + 1.17, respectively. Similarly, HbA1c levels between May 2019 without SMBG and May 2019 with SMBG were not statistically different. In this clinical study, we found that the request to avoid non-essential trips as a form of self-restraint during the country’s state of emergency did not affect plasma glucose control of patients with DM. We noted that the patients did not have signs of insulin resistance as their BMI on July 2019 and July 2020 were 24.4 + 3.6 and 24.4 + 3.6, respectively. Unexpectedly, the HbA1c levels were not affected by the absence or presence of SMBG. This could explain why HbA1c levels were not elevated, despite a temporarily sedentary lifestyle and a lack of exercise for a month. In addition, due to the self-restraint, the frequency of dining outside the house decreased, which could have contributed to the non-elevation of HbA1c levels.
